Abstract
A method and apparatus for installing a plurality of coated steel belts as tension members for an elevator system. A dispenser is employed that retains a plurality of rolled steel belts aligned vertically in said dispenser. An axel passing through the side walls of the dispenser and the centers of the steel belts rolls contained therein rotatably supports the steel belt rolls. When employing the disclosed method, equal lengths of the belts are pulled from the dispenser and clamped between two metal plates. A guide is then connected to the clamped plates which is used to feed the secured coated steel belts down the elevator shaft, around the sheave mechanism and back up the elevator shelf. The center core of the dispenser allows for the even systematic dispensing of steel belts so that equal lengths of the steel belts are fed simultaneous throughout the elevator system.
